Thesvin round HEPA filter elements are designed for handheld vacuums, robot vacuums, mattress cleaners, wet-dry vacs and car mini-vacs. They capture PM2.5, dust mites, pollen and hair from the dust cup airflow, preventing exhaust re-contamination. The filter is built to match your device's duct and dust cup dimensions, with options for washable PTFE media and custom frames. Thesvin manufactures in Zhongshan, Guangdong, China, and supplies OEM and ODM orders worldwide.
Fitment starts with the interface between the filter and the host device. Thesvin produces round filter elements to your exact outer diameter, thickness and pleat count, so the filter seats correctly in the dust cup and seals against the housing. A rubber sealing ring can be molded or assembled onto the frame to maintain airtightness and stop dust bypass. The frame itself can be made from environmentally friendly injection-molded plastic, and the overall shape is matched to the airflow path of the vacuum. Because every vacuum model has its own internal geometry, Thesvin works from your drawing, a 3D file, or an original old part to replicate the critical dimensions. This approach ensures the replacement filter locks in place, does not rattle, and maintains the designed seal throughout the service interval.
The filter media is selected for high-efficiency particle capture. Standard configurations use high-precision PTFE membrane, composite PP meltblown, or antibacterial treated filter paper. These media intercept fine dust, PM2.5, dust mites, pollen, hair and other particles that pass through the dust cup. By trapping these contaminants, the filter reduces secondary pollution from the exhaust and helps maintain a cleaner living environment. The pleated design provides a large filtration area in a compact round shape, which supports high dust holding capacity. For applications requiring odor control, an optional activated carbon layer can be added.

Thesvin operates a 50,000 m² production base with 20,000 m² of clean rooms across six workshops. The quality system is certified to ISO 9001, ISO 14001 and ISO 45001, and the company obtained IATF 16949 certification in 2024. Incoming materials are checked at IQC, process parameters are monitored at IPQC, and finished filters are inspected at OQC before shipment. The in-house CNAS-accredited laboratory can issue test reports for filtration efficiency, dust holding capacity, resistance and other performance data. Products comply with REACH and RoHS requirements, and compliance documents can be provided. With more than 20 years of filter development and manufacturing experience, Thesvin has supplied OEM and ODM filters to customers in Europe, the United States, Japan and South Korea. Multiple automated production lines support monthly output in the millions of pieces. For standard specifications, MOQ is typically 3,000 pieces; custom tooling projects generally start at 5,000 pieces. Lead time is 25–35 days after order confirmation, and larger quantities may require earlier scheduling. Samples of standard stock items can be provided free of charge (1–3 pieces), with the customer covering international courier costs. Custom samples may incur a fee, which is deductible from the bulk order.
To get an accurate quotation and fitment confirmation, please send us the following details: your device or vehicle model, the filter's dimensions or a drawing (or a photo of the old part), the required airflow or water flow (if applicable), operating conditions, and the estimated order quantity. Our engineering team will review your information and respond with a proposal. Contact Thesvin to start your inquiry.
Thesvin produces round HEPA filters to match your device's duct and dust cup dimensions. We work from your drawing, 3D file or an original old part to replicate the critical fitment features. A rubber sealing ring can be added to ensure airtightness. Please send us your device model and a photo of the old filter for confirmation.
Yes. You can send us a used filter or a clear photo with dimensions. Our engineers will measure the key dimensions and propose a matching specification. This is often the fastest way to ensure a correct fit.
Our round HEPA filters can achieve H11 to H13 efficiency, with ≥99.95% filtration efficiency for 0.3 μm particles. We also offer media options such as PTFE, PP meltblown and antibacterial filter paper to suit different performance and cost targets.
Yes. We provide 1–3 free samples of standard stock items, with the customer covering international courier costs. Custom samples may incur a fee, which is deductible from the bulk order. We encourage you to test the samples for fit and performance.
MOQ is typically 3,000 pieces for standard specifications and 5,000 pieces for custom tooling projects. Lead time is 25–35 days after order confirmation. For large quantities or peak seasons, we recommend confirming the production schedule in advance.
Replacement interval depends on usage and environment; for typical household use, we recommend every 3–6 months. We offer both non-washable and washable versions. Washable PTFE or modified PP media can be rinsed and reused for 6–12 months. Clear usage instructions are provided on the packaging.
Yes. We offer OEM and ODM services, including custom dimensions, pleat count, media selection, frame material, logo and packaging. With over 20 years of experience and more than 1,000 filter solutions developed, we can tailor the filter to your specifications.
